Geological context and results for the Ivory Coast rifted margin seismic experiment. The three panels show (a) topographic, (b) free air anomaly, and (c) magnetic anomaly contexts for the Deep Ivory Coast Basin and the Ivorian rifted margin. The Ivorian rifted margin is a lava-poor situated between the two well- preserved transform margins associated with the Saint Paul and Romanche Fracture Zones offshore of the Ivory Coast and Ghana. The Romanche FZ produces the Ivory Coast-Ghanaian Ridge (ICGR) that bounds the Deep Ivory Coast Basin. The domed mantle is correlated to the westernmost 30 mgal free air anomaly in the study area. The onset of seafloor spreading is marked by a 40 nT magnetic anomaly to the west, as well.

Except for Profile 1, which departs from a straight line to cross from the continental shelf to the denuded mantle dome to the incipient oceanic crust, each profile cuts straight across different parts of the Ivory Coast rifted margin. However, each section shows similar features: 1) continental crust and denuded mantle extended by seaward dipping detachment faults, 2) out-of-sequence detachment faults that further exhume the mantle to produce the characteristic dome, 3) increasing volcanism and magmatism in the seaward direction that eventually results in layered oceanic crust, and 4) anastomosing shear zones at the root of the out-of-sequence detachment faults that bring mantle intruded by igneous bodies near to the surface. A segment of the “M” reflector is labeled in Section 1 as a pink line.
